AXLE AND BEARN G ARRANGEMENT'.

' Application filed September 29, 1926. Serial No. 138,389.

This invention aims Vto provide, amongv other things, an axle and bearing arrange ment which will, to a very large extent, pre.- vent foreign matter collecting on the axle and finding its way into the bearings.

Another object of the invention is toV pro.-

vide an axle and bearing arrangement which can be quickly and cheaply manufactured, and which may be readily secured to a truck body. Y

Having thus briefly outlined the major objects of the invention l will now proceed to describe an embodiment thereof with the aid of the accompanying drawings inf which: a Figure l illustrates ofthe invention, and Y Figure 2 is a section on the line II-II of Figure l. f

Referring a sectional elevation to the drawings, l Vdesignates an axle reduced at its ends Qto receive wheels 3, which latterjare usually pressed onto the axle ends and the latterthen riveted over as indicated at Al, so thatV the wheels and axle all turn together. 'f

Around the axle -and'extending the full fr p I the fullv distance between said wheels, Vsupporting means on said housing, inward width between the wheels is an. annular housing 5 having bracketsy G'welded, .or otherwise secured, thereon toV support the body of a vehicle (not shown).` -Substan tially flush with the ends of the'housingand secured thereto, usually by welding, are inxward annular flanges Vwhich flitn snugly around lthe axle so that the latter may turn Afreely therein. The outer surfaces Aofthese flanges 7 bear against theinner surfaces of ing 5. I 4 v lllithinrthel housing aretwo roller bearthe wheels 1 as also do theends of the hous-v rnnononn V. ivrenonALD, or nennen?, MICHIGAN, Assrenon 'ro'ErWoRTH MANU- ings S'the louter ends of' which latterl rest against the inner surfaces of the flanges 7 and 9 indicatesl an annular spacer which holds the bearings in spaced relation to one another. The outside diameter of the spacer jis usually materially less than the bore 0f the housing' so thatv an'oil reservoir 10 ofV sufiicient size to contain aV good supply of lubricant is formedbetween them. The bore of the spacer should be somewhat larger than the diameter of the axle around which it is arranged.KV kAn lopening 11 is provided through the housing oppositethe spacer so that when thev plug l2 is removed lubricant may be pouredinto the reservoir. 1

lt will be noted that the housing with its inward flanges forms an enclosed unit provided with end openings of just suflicient' size lfor the. axle to rotate freely, and that the. flanges and the ends of the housing healagainst the inner-,sides 'of the wheels so that the possibility of dirt and foreignV 'i Vmatter entering the bearing has been reduced materially. lMoreover the size of the oil reservoir is such that a suflicient amount'of lubricant vmay be (contained therein lto last for a Vconsiderable time. i

While in the foregoing a'preferred embodiment of the invention has been described andV shown, it isA understood Vthat the con# struction is susceptible to such modilications soy as fall'within the scope of the appended claims."`

What I claim is;`

vl. An arrangement ofthe character vdescribed coinprising an `axle having a wheel secured to each` end, a housingof'uniform internall diameter vextendingV substantially flanges on' the outer ends ofA said'hou'sing having openings therethrough forthe pas-y esV '2. An arrangement of the character de- 'I scribed comprising yan axle havinga wheel secured to each VendsoV that said wheels and axle rotate together, a housing around said laxleextending substantially y'the full digs tance between said Wheels,supporting ineans on said housing adapted to receive a vehicle body, inward flanges secured to the ends of said housing having passages therethrough which it snugly around said axle, said flange outer 'surfacesA being in close proximity to said Wheels, bearings mounted around said axle within' said housing, an annular'spaeer around said axle between said bearings, said spacer being materially smaller than the bore of said housing thereby forming an oil reser-Y voir between said spacer and said housing bore, and means for filling said oil reservoir.
